Abstract

L'invention a pour objet un dispositif de mesure électronique (1) dont on cherche à améliorer la précision de la mesure, tout en compensant, en même temps les variations de mesure. A cet effet, il est prévu, dans un premier réglage du dispositif de mesure (1), de mémoriser un facteur de correction (K1) dans un élément de correction (7a). En régime normal, il est prévu d'appliquer une tension de contrôle (Up) qui est comparée avec une valeur de référence (R1) mémorisée lors du réglage. Lorsqu'une différence se présente entre les deux valeurs (R1, R2), on introduit un nouveau facteur de correction (K1, K2), lequel compense les variations dans le signal de mesure. Ce dispositif de mesure (1) convient particulièrement pour des compteurs électriques.
